So I give 5 stars, I read constantly the dust accumulates under the cover, I make then even once a month and clean with a lens cloth! But back to the review I give 5 stars because the shell does exactly what it should they protect my iPhone perfectly, which I know because I left my iPhone yesterday are accidentally on the roof of my car ^^ the absolute endurance test! Since the shell is a little slip they remained on the roof lie until I about 90kmh on the main road it was, then I heard a rumble as the wind the iPhone over the car roof slid and I saw my 800 phone fly in the rearview mirror. I saw it bounce three times then a car drove over it !! And what happened to my phone? 5 stars say yes everything: D Not a scratch, dent, or I glasbruch on iPhone XD konnts believe not! The shell has a few scratches where it is pitched, but it is also still fully functional! This envelope I can recommend to anyone who wants to be handed the whole remains and it takes into account from time to time to open the envelope to remove dust, which I personally find really not bad.
